Just when you think Kavanaugh had sucked up all the blame in the world....we are back....

    Yes, a significant problem. Not often discussed in the rush to get the cheering section set up.

    If you are an inquisitive logical thinker, then you are a Scientist.
    Being a correct Scientist is the difficult part.
    One has to have your theories and then test them out against the reality around us.

    Mars may wobble less, or not, but the very weak magnetic field will require a termite-like existence as the solar wind sterilizes all that it encounters.

    I am not a Scientist but I am a logical thinker. I agree with the mass in the northern hemisphere seems to be greater but I would like to add another variable.

    I think the wobble is decreasing because the Earth is trying to balance itself. An example could be a fluid damper on an engine. As it rotates, weights move around inside the fluid to balance the engine. Now the Earth is trying to do the same thing but the way it is doing it is by North America moving west and Asia is moving east. I believe that is why the Earth has the Ring of Fire.

    There are much smarter people on here than I when it comes to how it all works but I just think about things in the simplest ways to make them make sense. How close am I???

    Dear heavens, it was worse than I expected. And I had low expectations.

    Nonsense, Everyone knows It wobbles when Rosie Odonnel and Michaal Moore are in the same hemisphere.

    JOKE :)

    Did I read the article wrong? It did not say anything about ice mass changes being the only dynamic changes for changes in Earth wobble.
    As for the N body problem, there are a few closed solutions to the 3-body equations. Most dynamic models are not analytic, so one must use something like perturbation methods for solutions which fit reality.
    There is no model of real world that does not require real data for solution. A model does not just spit out a real world solution without data, therefor the need to fit variables to reality. If the model is analytic, closed solutions can be found but to give real results, there still must be real data measurements for each case applied to reality.

    Interestingly enough, the relationship of deep earthquakes and shallows seems well proven by insitu data, Dutchsinse has been calling it out for about 10 years and being bashed by mainstream science. There have been a lot of them going in the last few years as we head into GSM, perhaps that is a contributor in some way.

    Oh yea, he needs to have his wisdom consulted, I am sure he could find a way to fix the worrisome wobble.....:)

    That sort of was the intent, a never ending cycle of blame, even when it is hidden as "science".

    Let's just get everyone on the planet to move to the right to compensate for our evil misdeeds in using the resources available to improve our lives.
    I used to teach survival at a local university, although fun and challenging to figure out how to survive and get back home living at the level of subsistence and what you can accomplish on any given day would not be fun for an extended period of time and you quickly realize that even if you are skilled a simple change in short term weather can decimate the tribe.

    Does this mean the goofy Congressman who worried shifting population to one end of his island, meant it was going to tip over, has weather to consider too? Everything has to be about controlling climate by controlling hunmans, I get it.

    Correct. Tectonic movement is the dominant force that causes shifts in mass affecting spin, tilt, and wobble.

    The problem is that you can only model a two body gravitational interaction directly. No one has developed a solution for the N-body interaction that involves the effects of the sun, moon, and all the other planetary bodies combined, so it's measured indirectly with the collection of real data with a mathematical formula, as Legendre polynomials (think Fourier transform in three dimensions), adjusting a series of polynomials that describe estimated effects by changing the constants associated with each term to weight the observed effects. The same has to be applied for the Earth mass to account for shift in mass due to constant tectonic effects. The change in weight of the ice mass has an effect, but it's not alone in causing changes in the Earth's spin. To deal with it as though it's the only thing is a huge error.

    What are the "multibody" gravitational effects that were ignored? Is the "Bullcrap!" just because they tried using a model to discriminate and qualify between the various mass distributions which do cause the changing wobble of the Earth's rotation? It seemed that they just needed some mathematical research project to make up for not being able to do some important research along with some kind of implication that humans are important for that wobble and therefore some kind of change in climate. They must publish or perish.
